Research Topics

  • Fatigue mechanisms and new systems for high durable and ecological polymer composites.
  • Crack growth and interactions mechanisms in mechanical structure.
  • Development of advanced composite materials with high performances and properties for industrial applications.
  • Power transmitting mechanisms for CVT (Continuous Variable Transmissions) using metal and conventional V belts.

Research Contents

We believe, our laboratory is ahead in some branches of technology for developing new ecological polymer composites, high durable carbon fiber composites, novel structural system of CVT transmission with superior property and other effective concept for mechanical designs. Relating to our studies, at least ten papers are published annually in not only major domestic journals but also in a number of international journals.
Our laboratory has some collaboration with several companies to conduct specific researches related to the above subjects. We have also special subjects supported by the National Science Fund provided by the Ministry of Education, Culture, Sports, Science and Technology, Japan. Co-sponsorships with industry are welcomed as long as the results will be published in the future. International students are also welcomed. Do not hesitate to contact us.
